Taking place in the museum’s Discovery Hub on Wednesday 28 and Thursday 29 October, from 11am to 3pm, the activities will explore the vital role weather forecasting played in determining the timing of D-Day.

Visitors can discover the D-Day forecast made by Group Captain James Stagg and explore the science behind the weather through practical activities and demonstrations showing how clouds, rain and wind are created. Families can also get creative with weather-inspired crafts, handle collection objects, try on replica Second World War uniforms and enjoy toys and games for under-fives.

The activities are inspired by the film Pressure, which tells the story of the crucial weather forecasts and decisions made in the tense days leading up to D-Day. The film stars Andrew Scott as Group Captain James Stagg and Brendan Fraser as General Dwight D. Eisenhower.

Weather conditions were a crucial consideration for the Allied planners. Strong winds and rough seas could cause problems for landing craft and troops approaching the beaches, while low cloud could affect airborne operations, bombing missions and naval gunfire.

Visitors can continue exploring the story behind the film during their visit, as original props from Pressure are currently on display at The D-Day Story. Items include a Fortitude deception plan and identification cards for James Stagg and Irving Krick, giving visitors another opportunity to connect the film with the real history of D-Day.

Cllr Steve Pitt, Leader of Portsmouth City Council said: “Pressure shines a light on a fascinating part of the D-Day story, and these half-term activities give families the chance to explore that history for themselves. It’s a good opportunity to learn more about the decisions behind D-Day and enjoy some hands-on activities along the way.”

The props will remain on display until the end of November 2026. The half-term activities on 28 and 29 October are free with a museum ticket or annual pass, or £3 per child for those not visiting the museum.

Pressure is in cinemas now, coming soon to watch at home.
